Three very drawn out rounds - I only did two rounds and it took over 2 months and a few follow-up emails. The first was a zoom with the recruiter and the hiring manager. The second round was meeting team members in person then doing a math and writing test. I had one hour to complete both tests. I was told there was a third round, but was rejected before I got to that point.

4 rounds, 1: 30 min virtual with HR, very simple 2; 30 min virtual with HR and manager, very simple 3: 2.5 hour in person with manager plus 2 other people talking for half hour each followed by writing test and math quiz 4: 3.5 hour hour in person, meet with 5 people for half hour followed by case study Overall not very difficult, know your stuff about yourself and your motivations. It was a gauntlet though, 4 rounds is crazy.
